It appears the selected application either it's missing the control-center-starter dependency or there are issues to reach it, for example if it hasn't started yet. Is either of these the case? Anyways we're working to handle this error gracefully without crashing the UI.

@heruan The selected application has control-center-starter dependency. About the second cause, namely app has not started yet in that case, I'm not sure about that.
